AI Technical Summary
Existing electromagnetic shielded control cabinets present a contradiction in terms of heat dissipation and dust prevention. The gaps are too small, which affects the heat dissipation effect. After long-term use, the through holes are easily blocked by dust, resulting in excessively high equipment temperature and difficulty in cleaning.
The design incorporates staggered baffles and filters, with aluminum plates used for the staggered baffles to absorb electromagnetic fields. The removable filters facilitate cleaning, and a fan ensures effective heat dissipation and prevents dust from entering.
It achieves good electromagnetic shielding while improving heat dissipation efficiency and ease of cleaning, avoiding problems such as equipment overheating and dust accumulation.
